As visible in the photograph below,
bronze plates of figures run down the left side of the right door. There
are smaller images on the left door, but they are difficult to identify
and reproduce. The images show saints - and others!

St Peter
St Paul
San Zeno
Apologies for the quality of the reproduction. Peter is identifiable, as
he is holding a key: Paul's name is inscribed on his image.

St Helena Matilda of
Canossa Godfrey
St Helena is identifiable by the cross, her attribute. The other two
characters are rather interesting.
Matilda of Canossa, Margrave of Tuscany, was a wealthy and powerful
Italian aristocrat. She is best known for her support for the Pope,
Gregory VII. It was at her castle that the Holy Roman Emperor Henry IV,
stood in penance for three days in the snow while the pope relaxed in
the warm inside. She appears here because of her patronage of the Abbey.
The third figure is her husband,
Godfrey, duke of Upper Lorraine, also known as Godfrey the hunchback.
I have these identifications on good authority, but are they right? The
figure of Matilda appears to killing a dragon beneath her feet. The
image looks feminine, to be sure, but at first glance I thought of St
Michael, or, as there are no angel wings, St George.

The lowest image shows a sculptor hard
at work. A self portrait by one of the creators of the panels? No-one
knows.
